Specific embodiment

Below according to accompanying drawing, the invention will be further described：

As shown in Figure 1 and Figure 4, a kind of mould making model includes：Foaming mould 1 and crust mould 2；Foaming mould 1 With simulate human body head in crust mould 2 respectively to the cavity of chest model, the cavity 3 of foaming mould 1 is less than crust mould 2 Cavity 4；

Wherein, as depicted in figs. 1 and 2, foaming mould 1 is the box body using " convex " font structure, by protecgulum 101 and bonnet 102 two parts compositions, foaming mould 1 cavity 3 bottom is provided with support bar 111, the foaming mould 204 made for fixation（As Fig. 5 Shown）, protecgulum 101 and bonnet 102 are tightly locked using the mutual matched moulds of mould fix bar 114；Incidence position is provided with a groove 103, groove 103 is inserted in the middle of one setting round-meshed acrylic dividing plate 104, and head is divided into by acrylic dividing plate 104 with trunk Two parts, a cylinder head cervical region connector 105 is inserted at acrylic dividing plate 104 center；Described groove 103 both sides respectively have one convex Play 106, the effect of this projection 106 is that foaming model 204 cervical region of molding is formed two grooves 215（As shown in Figure 5）；

Protecgulum 101 head position side extends transversely through a positioning rod 107 setting circle column type incidence connector 105；

The eye position of protecgulum 101 has the through hole of two placement eyes cores 110, and bonnet 102 head position has a head Portion's sprue 1081, is placed 1 and is tightly connected with eyes core 110, the effect of described eyes core 110 and block 112 It is to be cavity by the eye position of the foaming model 204 of molding, different simulation eyeballs can be placed according to different demand；

Block 112 is fixed on box body bonnet 102 by pin rod 113；

The trunk position of bonnet 102 has two trunk sprues 1082 and three trunk steam vents 1092, box body bonnet 102 Head position have two head vent holes 1091, carry out foam model 204 make when, mould keeps flat makes head vent holes 1091 With trunk steam vent 1092 upwards；

As shown in Figure 3 and Figure 6, crust mould 2, a cube structure box body, base 201 concave structure, front lid 202 He Lid 203 is fixed on base 201 by mould fix bar 213 afterwards, and base 201 is provided with steam vent at bottom crust space 211 207, front lid 202 eye position is provided with simulation eyeball through hole 217, and eyes mandrel cavity 210 insertion, for making crust eye Between clear air, front lid 202 is additionally provided with sealed groove（In figure is not given）, as shown in Figure 4 and Figure 5, rear lid 203 is plugged with One block 206 carrying sprue 205；Support bar 212 is additionally provided with base 201 and supports foaming model 204, with base Gap was left before 201.

As shown in figure 5, foaming model 204 is the foaming model 204 made using foaming mould 1, there is head incidence position Cervical region connector 214, can make head left rotation and right rotation, and two grooves 215 of incidence position are used for fixing rubber finger sleeve 209（As Fig. 4）It is ensured that silica gel may not flow in incidence connector 214 when making crust；

As shown in figure 4, foaming model 204 is placed on the base 201 of crust mould 2, and merge front lid 202 and rear lid After 203, form a crust gap 211 with the cavity 4 of crust mould 2, this crust gap 211 is connected with sprue 205；

Before making model, first foaming mould 1 intracavity and foaming raw material are heated, temperature threshold scope is 38 degree～42 degree, Preferable temperature is 40 degree；Foaming raw material is polyurethane foam material；

First, make head frothing part, assemble foaming mould 1, in groove 103 interpolation of protecgulum 101 incidence position Enter an acrylic dividing plate 104, the center insertion cheese head cervical region connector 105 of acrylic dividing plate 104, fix by 111 Merge bonnet 102, insert locating rod 107 positioning cylinder forming head cervical region connector 105 in head position, foaming mould be upside down Put, make head vent holes 1091 upward, 1260 grams of head foaming raw materials being stirred from sprue 1081 injection of bonnet 102, In whipping process, the time must not exceed 15 seconds, and the time pouring foaming into must not exceed 10 seconds it is desirable to fall before foamed solidification Enter in cavity, because incidence position is provided with an acrylic dividing plate 104, make polyurethane foam material may not flow into trunk；

Secondly, make trunk frothing part, pour 2100 grams of trunk foaming materials into from the sprue 1028 of bonnet trunk position Material, in whipping process, mixing time must not exceed 15 seconds, and the time pouring foaming into must not exceed 10 seconds, foamed solidification it Before pour in cavity 3.

When making foaming mould, overall time must not exceed 25 seconds（This time is using hand operated mixing and to pour into required Time, the such as miscellaneous equipment time according to agitator etc is less than 25 seconds）, treat the foaming model ripening about half an hour Afterwards, take out internal foaming model 204 to carry out pruning burr, recessed in the foaming dummy head of molding and the neck junction of trunk The rubber finger sleeve 209 of one 70mm length of groove inner sleeve（Shown in Fig. 4）It is ensured that silica gel may not flow into incidence connector 214（Shown in Fig. 5） Interior；

Crust shown in Fig. 5 makes, and the foaming made by internal foaming mould model 204 is fixed on the bottom of crust mould On seat 201, eye locations place simulation eyeball, place sealing ring, and merge front lid 202 and rear lid 203 in sealed groove, Insertion head positioning bar 208 positioning foaming model 204, and crust mould 2 is locked, handstand mould, make steam vent 207 upward, Inject appropriate skin material from sprue 205, under 25 degree of room temperature, hardening time is 2.5 hours aftershapings to crust.

Block mold completes, the replaceable different simulation eyeball of the block mold completing（In figure is not given）.

The effect of the inside foaming of the present invention is to play support, loss of weight, reduces crust silica gel consumption reduces cost, and it is fixed to dissect Position；Crust adopts disposable low-pressure injection method to make, and can improve the globality of crust outward appearance, reduces die parting line it is ensured that producing The concordance of product.
